Be itknowmthat we, CHARLES E. BRIN- LEY, of Philadelphia, in the county of Philadelphi'a and State of Pennsylvania, and RUS- SELL H. BOWEN, of Palmyra, in the County oigBurlington and State of New Jersey, have invented certain new and useful Improvements in Wheels, whereof thevfollowing is a specification, reference being had to the acn 10 companying drawings.

2.0 and circumferential recesses upon opposite.

sides vof said; ilange, retaining collars ar` Y fyr'anged to slipl over said core, embrace respecy'tive spoke webs yof a pulley and be deformed,

by pressure; into engagement with the recesses of said core., so as to permanently secure the core and spoke webs inassembled relation without separate attaching means. Asv described, the contiguous perimeters of said core,lv collars and spoke webs may be of 3b polygonal configuration soas to positively prevent relative rotation of said members when secured as described. e Our invention comprises the various novel features of construction and arrangement hereinafter moredefinitely specified.

a modified form of retaining "collarQ shown in Fig. X, taken on the line XI, XI, in said figure. Y

-Referring to Figs. I to IV inclusive; the ulley rim comprises two axially alined`cyindrical sections 1, and 2, respectively in unitary relation with annular spoke webs 3,

central portions as shown in Fig. II, and sewithv the respective webs 3, and 4, as shown in Fig. II, and disposed in alternation in a ,"circular series as indicated in Fig. I. Said rim sections 1` and 2, are conveniently reinindicated in Fig. II, or be filled with rein forcing bars..

As shown In Fig. II, said webs 3, and 44:, are disposed upon respectively oppositesides unitary relation with the tubular core -1-2, intermediate of the length of the latter. Said corevcomprises undercut circumferential recesses 14, and 15, u on the `respecindicated in Figs. III and IV, -and so vproportioned as to sl'ide over the lopposite ends of the core 12, until their inwardly projecting flanges 19, and 20, encounter theV flange 11, on said core, and, thereupon',pressure axially directed on said collars toward said ange 11, results in the deformationof said flanges 19, and 20, to fill the recesses 14land 15, as shown in Fig. II, in permanent engagement with the core 12, and spoke vieles 32.11614.' v

It may be noted that in the form of our invention above described, the' outer walls 23, of the recesses 14,-and15, and theperim- 18, are of corresponding polygonal configuration, so that when the parts are assembled as shown in Fig. II, the inner edges of the spoke webs 3, and 4, assume a .correspondforced at theiropposite edges by the tubular flanges 8, and 9, which may be hollow-as .collars 17, and 18, are initiallyv shaped as XI,l is a sectional view ofthe'retaining collar and 4, which are divergently dished at their cured together by tubular riveted projections 5, and 6, which latter are in unitary relation.

of the annular flange 11, which extends in sov tively opposite sides of sai flange' 11,'jand nilo eters 24, of the retaining collars"17 and ing polygonal configuration, and relative rotation of the tubular core and spoke Webs is prevented. However, it is to be understood' that retaining collars oi circular coniiguration may be employed and said mem- `bers be prevented 'from relative rotation merely by their fricticnal engagement. For instance, as shown in Fig. V, the spoke iianges 27, and 28, are disposed upon res ectively opposite sides of the annular ange 29 ,which extends in unitary relation with the tubular core y30, intermediate of the length ol the latter. As indicated in Fig. VI, said core. 30, comprises circumferential recesses 32, and 33, which, in their initial form, 'shown in Fig. V1, are not undercut, but have cylindrical Walls arallel with' the axis of said core. The axia ly opposite faces of said recesses 32, and 33, are provided with.

circular ridges 35, and 36, which serve to bifurcate the approximate ledges of the retaining collars 38, and 39, so thatthe inner biturcated edges of said collars are embedded in the core 30, as indicated in Fig. V, With the undercut effect shown exaggerated in said iigure.

in Fig. V, may be primarily of the plane ended circular'form shown in Figs. VIII and IX, and as therein indicated, may each be a strip of sheet metal bentin annular form with its ends '40, in contact.

A'lthou h retaining collars of the form shown in igs. VIII, and IX, and above described, may be'conveniently constructed of vstrips of any malleable sheet metal, for instance steel; it is to be understood thatcast metal retaining ycollars similar to 'those shown in Figs. I, to IV, inclusive, may be i employed in the form of our invention shown shown in Fi s. V to XI, inclusive, relative i as indicated-in Fig. VII, comprising pockets rotation of t e spoke Webs 27, and 28, and

the tubular core 30, may be prevented by mere frictional engagement'incident to the deformation of the retaining collars in the recesses of said core; means for positively preventing such .movement may be provided 45 and 46, respectively in the lflange 29, and core 30, onopposite si es'- 'of each recess 32, and 33, so that When the retaining collars are deformed in said recesses the metal is caused to ioW into saidpockets and interlock therewith. Moreover, it is to be understoodthat a web connecting the rim loi a Wheel with its hub may be held as above` described by rictional lengagement collar 'lhe collars. 38, and 39, shown arance details of construction and arrangement herein set forth, as it is'obvious that various modifieations may be made therein without departing from the essential features of' our invention.
